Gill was an adult male SeaWing who was introduced in The Dragonet Prophecy. Before being captured by the SkyWings during the War of SandWing Succession, he ruled as the SeaWing king alongside his partner, Coral. After being deprived of water for months in the Sky Kingdom, he was killed by his daughter Tsunami in the SkyWing arena.
Little was known about Gill's personality, although Coral remembered him as 'being the perfect king,' describing him to have been smart, strong, persuasive, peaceful, gentle, and of a noble family. He was shown to be a good king, wanting to compromise rather than fight to end the War of SandWing Succession. He was said to have a way with words, such as when he was able to convince prisoners to stop fighting in Scarlet's arena. It was also stated that Gill adored Coral's writing. He went insane and murderous after he was imprisoned in Scarlet's arena and deprived of water for a long period of time.
He also seemed to care about SeaWing princesses very much, as he was devastated and furious when two of the female eggs were smashed in the prologue of Talons of Power. Though reasonable as he was, he was also prone to jumping to conclusions. This was shown when he blamed Turtle for not finding Snapper in time, despite Turtle only being a very young dragonet.
|King Gill led the SeaWing army in the War of SandWing Succession for a short period due to Queen Coral's commitment to keeping Anemone's egg safe, refusing to leave it in the Royal Hatchery. During one mission, he was captured and brought to Queen Scarlet's arena. He refused to fight for her amusement and attempted to start a prisoner revolution. For this, he was deprived of any drinking water for months, driving him to insanity, biting himself and drinking his own blood in his crazed state.|
The Dragonet Prophecy
|The Dragonet Prophecy|
|Gill was pitted against Tsunami after Scarlet had captured the dragonets of destiny, and was showing them off to Burn to celebrate her hatching day. He was punished after trying to start a prison revolution and stop all the dragons from fighting each other in the arena. Due to Queen Scarlet taking away his water for months, Gill had gone insane due to dehydration. Tsunami had no choice but to fight him. She had defeated Gill without killing him, but it caused Queen Scarlet to mock her. In retaliation, she snapped his neck, glaring at Scarlet with an expression that said: "I'm imagining this is you." For all of her time in the Sky Kingdom, Tsunami did not know that Gill was her father.|
|The Lost Heir|
|After finding out that he had been taken to the SkyWing Arena and subsequently killed, Queen Coral wondered why he would fight, saying that he would have simply talked the other dragons out of attacking. Tsunami then explained that Gill had been punished for doing so and that Scarlet had taken away all his water until he became extremely dehydrated, which had driven him mad. Tsunami asks why she is so troubled by this and Coral then told Tsunami that he was her father, overwhelming her with guilt. Coral was extremely saddened after the death of Gill and dismissed her council that day to mourn this death. Tsunami also mentions that she thought Shark had guessed the truth. Tsunami feels extremely guilty for killing Gill, both before and after learning he is her father. Blister also knew Tsunami had killed King Gill, threatening to reveal this to Queen Coral if the dragonets attempted to leave.|
|The Dark Secret|
|When Starflight entered Tsunami's dream with a dreamvisitor, he saw her strangling the skeleton shape of Gill. Anemone then arrived, and Tsunami tried explaining that she'd had no choice in killing their father. Anemone then strangled Gill herself while Tsunami was trying to hold her back. That was when Starflight decided to exit her nightmare and find another dragon's dream.|
|The Brightest Night|
|Tsunami mentioned Gill in the epilogue as one of the dragons who had never gotten to see the end of the war.|
The Jade Mountain Prophecy
|Talons of Power|
|In the prologue, Gill went to check on Abalone, who was guarding the eggs in the SeaWing Royal Hatchery, but Abalone had fallen ill and was growing worse. He had a strange, growing tumor on his neck. Gill then swam into the courtyard of the Deep Palace to ask for help, and he found Turtle with his hatchmates, Cerulean and Octopus. Turtle volunteered to help and tried to get Snapper. When he sent Turtle to find Snapper, he waits with Abalone, who is getting even sicker. He gets angrier and angrier while waiting for Turtle, but he finally leaves the Royal Hatchery to get Abalone's help. After he returns with the healers, Abalone is found unconscious with the two broken female eggs. Gill went into a rage and finds Turtle being made fun of by his brothers in the garden. He was angry with Turtle and scolded him fiercely. Gill then left to talk to Coral, who had both Abalone and Snapper executed. Grieving over their lost daughters, Queen Coral decided to name their next daughter Anemone. It is later shown that he forgave Turtle because Snapper was not even in the Deep Palace that day, but Gill got captured by the SkyWings before he could tell Turtle.|
|King Gill met with Blister when deciding what move to make next in the war. He tried to talk everyone into peace, even though he failed. After news of Tempest's assassination reached him, he was shown grieving while still trying to keep the peace among the infuriated dragons around him.|
Abalone was a good friend of Gill's. When he was inflicted with a growing tumor, Gill sought help quickly for him. When Abalone fainted in agony, Gill desperately asked for a healer first instead of protecting Coral's eggs. When Coral found out that the eggs were eventually destroyed, she ordered execution upon Abalone, in which Gill strongly disagreed with.
Gill had a loving relationship with Coral during his life. She thought highly of Gill, and even wrote a scroll on why she chose him. Coral knew he was trustworthy, and wanted him to run the kingdom while she stayed with her egg. Gill said he would do anything for her.
Tempest appeared to have a good relationship with Gill, as he sobbed heavily when she died.
He was angry at Turtle for not finding Snapper in time, which resulted in his daughters' deaths. Gill was resentful of his son from the incident but was sorry to have found out Snapper went off. According to Coral, Gill forgave Turtle for the incident when he was a dragonet, but he never got to tell Turtle before his death.
